Question about 2002 Ford E-Series
Check the idle air control valve motor (usually mounted on top of motor and has wires connected to it). You can thump it with a handle of a screwdriver and if that doesn't temporarily make the vehicle run properly then remove it, clean it with Goo Gone (turpentine or mineral spirits solution for cleaning up gummy residue) and Qtips for your ears, both available at Walmart, and air dry the part for 10 minutes (flammables), then reassemble and try again. Also check for loose fitting air
hose between the filter box and the motor and check for possible holes or small melted thin areas on the rubber hoses between the PCV valve and the motor. These are the most likely causes of the vehicle not idling properly when you put the vehicle in gear.
